Combobox - Dialog Exits When Enter Pressed?
Aug 29, 2009I'm designing a Windows Forms Application, and there is a dialog that should NOT exit when the enter key is pressed, instead it has to validate data first, in case enter was pressed after changing the text of a ComboBox. I've tried by telling it what to do on KeyPress event of the ComboBox if e is the Enter key:
[Code]...
But no success so far. When the Enter key is pressed, even with the ComboBox on focus, the whole dialog is closed, returning to the previous form. The validation is NOT done at all, and it has to be done before exiting. In fact, I don't even want to exit on the form's enter KeyPress, the only purpose of the enter key on the whole dialog is to validate the ComboBox (but only when in focus, for the sake of an intuitive UI). I've also tried appending the validation to the KeyPress event of the whole dialog's form, if the key is Enter. NO SUCCESS! It's like my code wasn't there at all.

VS 2008 - Program Starts And Exits Immediately
Dec 6, 2010I copied a project I wrote on my XP machine to my other computer with Windows 7 64-bit. When I run it through VS2008 it exits immediately. It does not run a single line of code. The exit code is 0. I need to post what else it says. But I did find a posting about this saying the path to the temp files may be wrong for it but he did not know how to change this. If I create a new peoject and put a command button on it, the program runs. So I was wondering if it is something like the temp files or something else. The machine runs a compiled .exe of the program from the XP machone when installed on the Windows 7 machine. So I do not think it is the program not being compatible.
View 5 RepliesAcrobat Hangs After User Manually Exits Program
Jun 4, 2012I'm currently having an issue with VB.Net and Adobe Acrobat. The issue comes from exiting Acrobat but the Windows Taskbar still states that there is an Acrobat.exe process open. I have tried using Marshal.ReleaseComObject(), but it still hangs there. I do not want to have to rely on the "End Process" option on the Task bar in order to remove it.
Below is a snippet of the code that I am try to using:
Try
'Tries To Close Acrobat Application
acrobatApp.Exit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(javaScriptObj)
[Code] .....
Although I am not sure if this could be a problem - I run a javascript saveAs script on the Acrobat side in order to make a copy of the file. This also could be a reason why it is hanging, but I ruled it out based on basic knowledge of saving files and exiting from other Acrobat/Microsoft Programs. Acrobat only closes when my application ends. (Currently) I am trying to make it consider the case if a user manually closes the Acrobat application.
Saving Data Which Would Need To Be Updated Every Time The User Exits The Program
Aug 21, 2011I want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

App Name Does Not Show Up In Open With... Dialog?
Jul 29, 2009After deploying and installing my application I use the app to create and save a file with my own file extension. After the file is created I right-click on the file and select Open With.. so that I can associate this file extension with my application. In the Open With dialog I use the Browse button to find my application and select it. In the Open With dialog the application icon is shown, but the name of the app is blank (looks like an empty string). Can anyone tell me why this might be happening? I've looked at the Registry, which shows the correct app, but every time I open the Open With dialog only the application icon is displayed, no name.

VS 2010 Show Dialog From A Hidden Form?
Oct 6, 2011I'm trying to create a program that will look at a website and check it for updates, similar to an RSS feed. It then will show a dialog (Form2) that will inform the user that there is an update.Form1 is used as the configuration form and is able to be shown via a notify icon in the system tray, which is on Form1.Originally I would have Form1 hidden via Me.Hide() and then run a timer which would check for the updates and call Form2.ShowDialog() when there's an update, I found out however, that if Form1 is hidden, the dialog will not show.
Next I tried not Hiding the form, but instead setting its ShowinTaskbar property to False. At this point the program functions correctly, however when I minimize Form1 it sits in a shrunken window near the task bar... Is there any way to completely hide Form1 (when minimized), and allow Form2 to be shown as a dialog?

Print Dialog Does Not Show Up In Crystal Report Viewer On 64 Bit Machine
Mar 25, 2010I have a client, who is running Windows 2008 Server 64 bit. He is running our software, it has a built in crystal report viewer functionality. The print dialogue just wouldn't work no matter what. It worked on our 32 bit box and we verified it. I verified it on our 64 bit box, and the print dialogue didn't open either. I did some research online. And one suggestion is to set m_printDlg.UseEXDialog = True. I tried that, but that did not work either...
Here is the code snippet.

View 3 RepliesShow Windows'Open With' Dialog When No File Association Found
Mar 2, 2009I am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.
View 8 RepliesForms :: Showing The Show Dialog Window On Front When Clicking With Mouse?
Mar 25, 2009My Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id

Apr 4, 2009As a continuation of my previous posting, which we were able to resolve, I am running into the same problem again, due to being unable to use frmForm1.Show().In my last situation I had to use frmForm1.ShowDialog(), which worked in that case, as it called another form, for example frmForm2.However, now I have a program that is sometimes required to recal frmForm1, and I get the following message: �Close the form before calling ShowDialog.But, in frmForm1,I include, Me.Hide() and Me.Close(). Also, before recalling frmForm1, from a procedure under Main(), I have added the following
frmForm1.Close()
To me that would suggest the form is closed, dead and buried, but the programme still stops at the point of:
frmForm1.ShowDialog()
With the same message: �Close the form before calling ShowDialog.
